A veiy singulai- plant, closely aUied to none in the Order Eepaticæ-, it forms pale sdvery patches at the roots
of ferns, &c., in the woods, hut has only been found fruiting iu New Zealand, where, as in Tasm.aiiia also, it is probably
abundant. In the specimens from Lord Auckland’s group the fr-onds m-e hariUy sinuated at the margins and
often formed of only one or two series of cells smroimding the axis ; in those from more Northern Latitudes other
series of ceUs are superadded, the fronds are more compressed, and their margins so sinuated from the ii-regidarly
placed cells as to resemble the nicUments of leaves. Though the waEs of the ceUs are exceedingly deUcate, the whole
plant is of a rigid textm-e, and very slowly recovers itseE when moistened ; this somewhat horny consistency of the
frond, resembUiig some Sertulariæ, has suggested to us the generic name. The drawing w-as made before the fructification
was obseiwed, by Mr. Wilson, upon the New Zealand specimens.

This is one of the numerous frondose Eepaticæ which cover the ground so abundantly in the humid regions of
the South; they eridently belong to many species, but having never been found in fructification, it is exceedingly
difficult to distinguish the species by the foi-m and texture of their variable fronds, and stiU more to determine the
genera to which they belong. Tbe present, of which our specimens are but imperfect, seems identical ivith a very
common New Zealand plant, wMch abounds in moist places, and especiaUy near cataracts.

This being quite mdike any of tbe hitherto described Hepaticee, we attached the generic name of Biecia from a certain
resemblance in the form of its frond to several species of that genus, but tbe plant is more probably allied to some
frondose Jungermannia,—J. epiphylla for instance. Tbe concave frond with entire coxmivent lobes, partakes of tbe
habit of that of Collema granulatum, Acb., but our plant is certainly a Hepática.

XXXV. FUNGI, L.
(By the Rev. M. J. Berk eley .)
The niunber of Fungi collected during the Expedition is very small, m proportion to that of other cryptogamic
plants, with the exception of those foimd in New Zealand and Van Diemen’s Land. In the more southem localities,
Fungi may naturally be expected to cease, sooner than Algoe, lAchens, and Mosses ; and accordingly, from
such localities, the amount of species is trifling indeed. Even where the degree of cold is not sufficient to prevent
the growth of Fungi, their fructification is materially affected ; and thus, in the higher forms, the hymenium will
frequently be found barren ; while, in some hypogæous species, transfonnations of the sporophores themselves take
place, causing the fructifying mass to assume a very anomalous appearance. Some species indeed, as Filohokts
crystallinus and Hydrophora stercorea-, seem to flourish most in the frosty nights of autumn, and the species of the
genus Chatonyplia and Lanosa nivalis thrive either beneath or upon the surface of the snow ; but I know of no other
exceptions to the more general habit of these species, and in these cases, the temperature either does not descend
below the freezing point, or, as in the case of the Cliætonyplia, vegetation takes place only when the surface of the
snow is just melting under the influence of the sun.
Amongst the more northern islands visited by the Expedition it is probable that some interesting forms, had
time allowed, would have rewarded fm-ther research ; though, indeed, constant attention was directed, even to the
obscurest forms of vegetation, wherever cfrcumstances would peimit. As it is, there is a considerable number of
new species to describe, and some of them possess much interest, especiaRy a new Cyttaria from Cape Horn, the
specimens of which are so numerous as to afford an exceRent opportunity of examining the structure of this curious
genus ; wliich, Rke Podisonia and Gynmosporangium, which infest certain species of Juniper, developes itself on the
living branchlets of the deciduous-leaved Beech. Some of the species, like those of other Cryptogams, are identical
ivith plants of the Northern Hemisphere ; and this is especiaRy observable in New Zealand, where the identity is
not confined to those families in wliich it is more usual.
